Title: Shaft and bearing
Inventor: NATORI EIJI
IPC: F16C32/04
Filed: 1989-03-17
Abstract: PURPOSE:To obtain stable rotation even in a high speed revolution in which a superconductive material and a permanent magnet are used, by utilizing a radially magnetized magnet or a magnet for combined use for both radially magnetization and an axial magnetization, for the shaft and bearing. CONSTITUTION:In manufacturing a bearing 1, a magnetic field is impressed to a molten PPS (polyphenylene sulfite) in both radial direction 'a' and axial direction 'b', using a magnet field injection molding machine, so that magnetic powder having magnetic anisotropy is oriented. After this, the PPS is solidified for forming. In addition, this injection moulded product undergoes multipolar magnetization in both radial direction 'a' and axial direction 'b'. In manufacturing a rotary shaft 2, the powder of 13 i2O3, PbO, SrCO3, CaCO3, and CuO is mixed and dispersed, first. Next, it is melted for molding and then annealed in the oxygen-rich atmosphere to complete the manufacturing process. The bearing thus manufactured can have stable, non-contact structure, because the surface flux of the magnet is powerful and uniform and moreover it gives strong resiliency due to the Meissner effect.

Title: Semiconductor switch
Inventor: OKUTSU MITSUHIKO
IPC: H03K17/732
Filed: 1984-03-30
Abstract: PURPOSE:To decrease power consumption by turning on a switch element to drive a load and a thyristor at the same time thereby using a thyristor while avoiding a complicated circuit. CONSTITUTION:When an input IN is brought into an H level and a transistor (TR)Q5 is turned on, a thyristor SCR1 is turnedon to charge a piezoelectric element CL. Then the input IN is brought into an L level, a TRQ2 is turned on and brought into the saturating state, then the discharge current of the piezoelectric element CL flows through a resistor RL, a diode D1 and the TRQ2 and also a gate potential VG of the thyristor SCR1 is lowered nearly to an earth potential. In this case, a cathode potential V0 of the thyristor SCR1 is brought into a state higher than the gate VG by a forward voltage of the diode D1, biased reversely and the thyristor SCR1 is turned off. Thus, the piezoelectric element is driven for charge/discharge with a simple circuit employing the thyristor.

IPC: B65C9/25
Filed: 1989-03-17
Abstract: PURPOSE:To prevent the deformation of a label and container at the time of an in-mold molding and to prevent the impairment of the printing surface of the label by forming a film layer for adhesion which is thermally melted by the heat of the container at the time of the in-mold molding on the rear surface of an unstretched plastic base film formed with the printing surface on the rear surface.

IPC: G11B7/0055
Filed: 1995-03-24
Abstract: PURPOSE: To obtain an optical recording medium and its reproducing method which realizes a superhigh resolution mechanism with a simple structure. CONSTITUTION: This optical recording medium is produced by forming a silicon nitride base layer 2 of 80nm thickness on a disk substrate 1 and further successively forming a TbFeCo recording layer 3, silicon nitride interference layer 4 and aluminum reflecting layer 5 thereon. The substrate 1 is, for example, a disk type substrate and consists of polycarbonate as a plastic material containing dispersion of a copper phthalocyanine complex as a phthalocyanine deriv. Guide grooves 6 are formed on the substrate 1. In the center and near the center of the beam spot of laser light where the intensity is high, an excited state of the copper phthalocyanine complex is caused by the light in the substrate 1 so that strong absorption by the ground state decreases to increase the transmittance.  On the other hand, in the peripheral part of the beam spot of laser light where the intensity is low, the ground state causes strong absorption to decrease the transmittance of the, substrate 1.

IPC: H04W16/02
Filed: 1994-03-08
Abstract: PURPOSE: To obtain the cellular communication system that increases a channel capacity in a fixed frequency spectrum by re-using the spectrum over a spherical surface efficiently. CONSTITUTION: An orbit satellite 12 projects a footprint 30 on the earth. Each footprint 30 is divided into cells 28. The footprints by neighboring satellites are overlapped with each other and the overlap amount is increased as the satellites approaches one of the poles from the equator. A channel set is assigned in cells in a reference footprint. This assignment is being propagated to all footprints except footprints in existence adjacent to one side of a seam between orbits 14 on which satellites are travelled in opposite directions. Each satellite stores the assignment of the channel set to the cell at various points on its orbit. All satellites switch their communication parameters simultaneously depending on the assignment of a channel set.

Title: Mode output changeover circuit
Inventor: KAWASE HIROSHI
IPC: H03K17/00
Filed: 1990-03-16
Abstract: PURPOSE:To attain quiet and light mode changeover operation and to simplify the circuit constitution by resetting a mode output state by a signal storage circuit. CONSTITUTION:A reset pulse is generated from a reset circuit 12 by operating a different switch and the reset pulse resets a current mode output from a signal storage circuit 11. The signal storage circuit 11 stores only a mode output of a switch operated newly by the reset. In this case, so-called momentary pushbutton switches whose contacts are closed only when they are depressed are adopted for switches 101-10n. Thus, the operation is light and quiet more than that by a lock pushbutton switch and the circuit constitution is made simpler than a circuit making switching by CPU control.
